The Wind: Your Biggest Red Flag
In San Pedro, the wind usually blows from the East. That’s good because the Barrier Reef acts like a giant wall, breaking the waves and keeping the “inside” water calm. But when the wind shifts or hits speeds over 15-20 knots, things change.If the wind is coming from the North – what we call a “Norther” – the water gets choppy fast.

We call this “marine snow.”If you are a photography nerd following photography tips for underwater snorkeling in Belize, bad visibility is your worst nightmare. You’ll end up with photos that look like you took them inside a washing machine. Rain alone doesn’t usually ruin visibility, but a heavy storm can wash silt from the mangroves into the sea. If you can’t see your own fins when you’re standing on the dock, the reef probably isn’t going to be much clearer.
